There are two member classes, one for PBCs and TOCs and one for NTRBs and NTSPs.
This is a standard structure for peak bodies with different types of organisations in its membership and it allows for a lot of flexibility in how the organisation is managed. Meetings can be tailored for each member class and specific issues, in addition to meetings of the Council of members for representatives from all NNTC members.
The structure of the NNTC Board of Directors is 10 Directors, 4 from the NTRB/NTSP member class, 4 from the PBC/TOC member class and two co-opted Directors. This ensures that the Board represents the interests of all members of the NNTC.
